Script to display ALL the reserved addresses configured on the DHCP server.

  • Article

The Microsoft DHCP server provides show command to display reserved addresses configured at a particular scope level. But diplaying ALL the reserved addresses configured in ALL the scopes in the server is not possible with a single command.

 You can make use of the below script (Batch File) to display the reservations for all the scopes configured in the server. An intermidiate file named "display.nsh" will be created in the current folder but it gets deleted once the script execution completes.

 

Note:   The below script contents are for running as a batch file. If you are running directly on the console (ie not as a batch file), please replace all occurrences of %%i in the script with %i.

 

 

Script for DHCPV4 (Display_DHCPV4_Reservations.bat)

*********************************************************************************************************

@echo off

del display.nsh > nul 2> nul

for /F "skip=4 tokens=1 delims== " %%i in ('netsh dhcp server show scope') do if NOT %%i == Total if NOT %%i == Command echo dhcp server scope %%i show reservedip >> display.nsh

netsh -f display.nsh

del display.nsh > nul 2> nul

Script for DHCPV6 (Display_DHCPV6_Reservations.bat)

 

*********************************************************************************************************
